Title: Straightening method for bend of pipe
Inventor: KONDO TOMIO
IPC: B21D3/04
Filed: 1988-03-29
Abstract: PURPOSE:To shorten a bend at the tip of a pipe and to improve the yield by making the interval between a pair of rollers on the outlet side and a guide roller shorter than the intervals between pairs of rollers and at the same time enabling the guide roller to touch and detach the pipe in the passing region and giving an excessive bend to the tip part of the pipe. CONSTITUTION:In a straightening machine having pairs 1, 2, 3 of rollers faces up and down and the guide roller 4 on the lower side of the outlet side pass line, the span between the pair 3 of roller on the outlet side and the guide roller 4 is provided to be shorter than the spans among the pairs 1, 2, 3 of rollers. The center of the pair 2 of rollers is offset upward to the center line between the pairs 1, 3 of rollers. Besides, the guide roller 4 is provided with a lift 4a to make the quantity of bend deltaB variable. Correspondingly, in the pipe T, the length of the bend on the tip of the pipe is shortened by the pairs 1, 2, 3 of rollers to the span length between the pair 3 of rollers and the guide roller 4 as a result of not only an offset effect and a crush effect but another offset effect between the pair 3 of rollers having a short span and the guide roller 4.

Title: Printing of metal paste on green sheet
Inventor: NARUSE MASATO
IPC: H05K3/40
Filed: 1990-03-26
Abstract: PURPOSE:To prevent the generation of the deficit of via lands covering via holes filled with metal powder by a method wherein the thixotropy index of the metal paste is specified. CONSTITUTION:Prescribed conductor patterns 5 are printed on the surface of a green sheet 1 with a metal paste by a screen printing method. The paste is a copper paste containing copper powder and an organic solvent as its main components and it is desirable to set a thixotropy index of the metal paste into 5 to 7. In case the index is smaller than 5, a reduction in the viscosity of the metal paste at the time of printing becomes too little, the paste can not be scraped out sufficiently from a printing plate toward the sheet 1 and conductor materials 4 and there is a possibility that the film thickness of the patterns 5 become thin. In case the thixotropy index exceeds 7, when the printing plate is removed, the paste applied on the sheet 1 and the materials 4 is easily peeled off to the side of the printing plate and the generation rate of the deficit of via lands is increased.

Title: Membrane switch
Inventor: KOBAYASHI SHOICHI
IPC: H01H13/02
Filed: 1990-03-29
Abstract: PURPOSE:To obtain a transparent membrane switch with which production of interference fringes is prevented and with which bounce at the time of switching action is restricted by forming a number of fine irregularities at least in a surface of one glass substrate facing the other glass substrate, and forming electrodes in the irregular surface. CONSTITUTION:A membrane switch consists of a lower glass substrate having an upper surface of an irregular surface 3a where a number of fine irregularities are formed, with lower electrodes 4 patterned in the irregular surface 3a. Light from a light source is irregularly reflected at the irregular surface 3a of the lower glass substrate 3, so interference fringes are not generated, and a high grade membrane switch can be achieved. The lower electrodes 4 of a form shaped along the irregular surface 3a has fine protrusions 4a, and upper electrodes 2 are put to get in point contact with the fine protrusions 4a for changing into a switch-on condition, so bounce in a switching action can be restricted compared to a case where both electrodes get in surface contact with each other, thereby a membrane switch of a higher responsiveness can be obtained.

Abstract: PURPOSE:To improve follow-up performance to a target impression voltage value, and heighten control accuracy by providing an adding means to output a correction voltage value found according to voltage follow-up speed corrected by a voltage follow-up speed correcting means after it is added to a target voltage value. CONSTITUTION:Voltage impressed upon a motor is fed back, and voltage deviation VE to target voltage is found, and a voltage follow-up speed quantity DELTAVA being a proportional term is calculated. A rate of change of the voltage deviation VE is found, and judgment is made on whether the absolute value becomes large or not. When it becomes large, a prescribed correction value V is given, and when it becomes small, (DELTAVB=0) is realized. DELTAVB is added to DELTAVA, and DELTAVC is obtained. A differential value DELTAVM of a voltage value VM is calculated, and deviation Eu (=DELTAVC-DELTAVM) to VC is found, and it is outputted to an integral term 17. As a result, a correction value DELTAC is converted into a pulse. A basic value CB of output is calculated from target voltage VO, and a final indication voltage value (C=CB+DELTAC) is outputted to a driver 20 together with DELTAC from the integral term 17.

Title: Vertical deflection circuit
Inventor: TAKAGI KATSUHIRO
IPC: H04N3/16
Filed: 1980-06-12
Abstract: PURPOSE:To perform vertical oscillation not requiring external trigger pulse, by triggering a pump-up circuit with a pulse produced at the input side of a vertical deflection output circuit. CONSTITUTION:A negative pulse detecting circuit 8 which detects a negative output pulse of a vertical deflection drive circuit 1 triggers a pump-up circuit 3. In a scanning period, an input voltage of a vertical deflection output circuit 2 is the superposition between a bias voltage of the 1st stage element and a saw tooth wave voltage applied to a terminal 12. On the other hand, at blanking period, since a feedback loop consisting of a vertical deflection drive circuit 1, output circuit 2 and blanking circuit 4 is cut off due to a blanking pulse produced at a vertical deflection coil 7, the 1st stage element of the output circuit 2 is cut off and a negative pulse is produced. A vertical deflection circuit made easy for circuit integration is constituted by taking this pulse as a pump-up trigger pulse.
